Rutherford claimed that at the center of an atom there was a very tiny, very dense, positively charged part called a nucleus, surrounded by electrons at a distance.
that nucleus is at the centre of the atom. it has positive charge
A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
This was an idea of Ernest Rutherford (1871-1937) from 1911.

The gold-foil experiment
The experiments were being done by Ernest Marsden, and Hans Geiger, under the supervision of Ernest Rutherford.
The (cell) nucleus is generally believed to have been discovered by Antonie van Leeuwenhoek. The nucleus of the atom was discovered by Ernest Rutherford.

in 1897
Ernest Rutherford discovered that the nucleus of an atom has a positive charge and discovered the evidence to show the electron field surrounding the nucleus in an atom.
Ernest Rutherford
The discovery of the nucleus is typically credited to Ernest Rutherford, an English physicist of the early 1900s. Rutherford first came up with the idea of a nucleus as a result of his gold foil experiments.
